Freeze-drying (freeze-drying for short) is a stable process of drying materials. It freezes the water-containing materials into solids, and then sublimates the water from the solids to the air, removing the water to preserve the materials.
The relative position of the particles has been fixed, and there is no surface tension on the gas-liquid interface between the two particles. As the solvent continues to distill, the solid-phase bridge will continue to decrease, but the relative position between the two particles will not change until the solid-phase bridge disappears completely.
